I have the same kit in the stash, and if i remember right, this is the aircraft depicted in the white scheme.
That deffinatly looks like white to me. They were intended to be used for the Stalingrad airlift, but apparently they couldn't find big enough airfields, so there use was cancelled.
Would love to see some pics of your build and hear what you think of it.
I am a Norfolk man and i glory in being so
